LUBRICATING- :PAIDV Application filed January 30, i929, Serial No.

The presentinvention relates to improvements in lubricating pads foraxle-boxes and concernsmore especially/an improved lubricating pad foruse n axle-boxes of railway vehicles.

The primary object of 'this invention is to provide a very compact andelastic lubricating pad which shall be placed under the wheel axle intheaxle-box and shall stay in the right position without'losing parts ofwool or cotton as ordinarily happens with the waste cotton generallyused for the same object.

Another object is to provide a lubricating pad which will stand a longwear and which, to that effect, can be used successively on every side,owing to its great elasticity. i

A further and most important object is to rovide inside the pad anelastic frame whlch shall keep inside the wool covering and shall notcut thru the covering, thus causing damage to the axle or to theaxle-box.

A still further object is to provide an improved lubricating pad adaptedto simplify and facilitate the man facture of the same.

These objects are accomplished by the improved construction of thelubricating pad hereinafter disclosed and illustrated by way of examplein the accompanying drawings in which:

Fig. 1 is a View of the inner frame.

Fig. 2 is a transverse section along the axis of the frame showing thecomplete pad.

Fig. 3 is a transverse section of the same, perpendicular to the axis ofthe frame.

A thin sheet of steel 1, of proper dimensions is bent in shape of acylinder, shown in Fig. l. The two edges meeting are riveted to eachother thru the holes 3`or can be sealong the edges of the cylinder andsmall projecting parts 2, formed inte al with the sheet l, are providedalong t e same'edges f and are somewhat bent towards the inside of thecylinder.

around this 'layer or felt is sewn a covering 6 made of wool or cottonor a nnxture of The intermediate layer 5 or felt, provides a suitablestuin'g for the covering 6, and is protected from beingcut by the sharpedges of the frame 1 by the projecting parts 2. y
